5.3 Expansion module MAC00-B41
5.3.12 Connecting a balanced/push-pull signal to the Multifunction I/O
The drawing below shows how to connect a balanced or push-pull signal source to the
MAC00-B41 multifunction I/O's. Use twisted-pair cable for the balanced signals in order
to ensure noise immunity.
Note: If inputs are used in pulse-direction format input A (Ax+/Ax-) is pulse input and
input B (Bx+/Bx-) is direction input.
Warning: Voltages higher than 5V must under no circumstance be connected directly to
the input since this will damage the input permanently. Use a proper resistor as indicated
in the table below.

Warning:
Never connect voltages
higher than 5V directly to
the A or B terminals since
this can damage the inputs.
